Abstract

L’invention concerne un dispositif (1) comprenant : - un support (2), - un panneau réfléchissant (3) monté mobile sur le support (2) et propre à réfléchir un rayonnement lumineux incident (R1) de manière à générer un rayonnement lumineux réfléchi (R2) selon une direction principale de réflexion, - un moteur propre à déplacer le panneau réfléchissant (3) par rapport au support (2), - un capteur (5) comprenant au moins deux cellules photoélectriques, chaque cellule photoélectrique étant propre à générer un signal électrique en fonction d’une intensité du rayonnement lumineux réfléchi (R2) reçu par la cellule photoélectrique, une différence entre les signaux électriques étant représentative d’un décalage angulaire entre la direction principale de réflexion et une direction de réflexion cible, - un module de commande propre à commander le moteur en fonction de la différence entre les signaux électriques générés par les cellules photoélectriques pour déplacer le panneau réfléchissant (3) de manière à aligner la direction principale de réflexion avec la direction de réflexion cible. Figure pour l’abrégé : Figure 2The invention relates to a device (1) comprising: - a support (2), - a reflective panel (3) movably mounted on the support (2) and capable of reflecting incident light radiation (R1) so as to generate reflected light (R2) along a main direction of reflection, - a motor capable of moving the reflective panel (3) relative to the support (2), - a sensor (5) comprising at least two photoelectric cells, each photoelectric cell being its own generating an electric signal as a function of an intensity of the reflected light radiation (R2) received by the photoelectric cell, a difference between the electric signals being representative of an angular shift between the main direction of reflection and a target direction of reflection, - a control module capable of controlling the motor according to the difference between the electrical signals generated by the photoelectric cells to move the reflective panel ( 3) so as to align the main direction of reflection with the target direction of reflection.
